I am running Exchange 2003 under Windows SBS 2003. Many of our users use Outlook Web Access to access their mailboxes when not in the office.
In the last week or so OWA has stopped functioning twice. Users see the login page, but when the enter their user name and password, the page just sits there for a while and then a "Page cannot be displayed" type error appears in the in browser. The only way I know of to fix this is to reboot the server. Everything else appears to work fine, including access to Exchange mailboxes using Outlook on PCs in the office, so I don't think it's a problem with the information store. I really have no idea on even how to begin troubleshooting this problem, so I'd appreciate any help with the following items:
1. Until I manage to solve this problem, is there a way to restart OWA without rebooting the server? I mean, by restarting particular services?
2. What might be causing this problem in the first place? Is there something specific I should be looking for in the event logs, because at first glance, I didn't see anything that might be related to this problem.
